Answer any question about your body — instantly, personally, accurately
Tell you exactly what to eat, when, and why — based on your cycle phase
Sync your workouts to your hormones so you stop burning out and start burning fat
Explain why you feel the way you feel — and what to actually do about it
Be there at 2am when you're spiralling about your skin, your weight, your energy
Instead of Googling for hours, booking expensive consultations, or buying supplements you don't need — you can just ask Bestie.
"I eat well and work out but I can't shift the weight. What am I doing wrong?"
"My skin breaks out every month in the same spot. Is that hormonal?"
"I'm at a restaurant — which option on this menu is actually good for my hormones?"
"I made eggs and avocado for breakfast. How do I make this more hormone-balancing?"
"Why am I SO tired on Day 22 even when I sleep 8 hours?"
"I've been tracking my cycle for years but I still don't know what to do with the information."
"I should be further along by now."
"What if my body is just broken?"
"What if I'm doing everything right and it still won't work for me?"
Every woman hits this point.
You are not alone.
Life doesn't stop for your hormones. You're at a work dinner and you don't know what to order. You're at the gym and you don't know if you should push or rest. You're standing in your kitchen at 7am trying to make a healthy breakfast and you don't know if it's actually helping or hurting.
That's exactly what Bestie is for.
You know you eat "healthy" but you still feel bloated, tired, and stuck
You track your cycle but have no idea what to actually do with that information
You've tried every diet and the weight always comes back
You push through workouts on your worst days and wonder why you're not seeing results
You Google your symptoms and get advice that was clearly written for a man's body
Your skin breaks out, your mood crashes, your energy disappears — and no one can explain why
You spend money on supplements, programs, and consultations — but nothing sticks
You feel like your body is working against you
You want to finally understand what's actually going on inside — and what to do about it
The Simple Truth

You weren't failing the programs. The programs were failing you.

"I asked Ask Aggie what to order at a restaurant and she gave me the most specific, helpful answer I've ever gotten from any app or doctor. I've been using it every single day for 3 months. My skin is clear, I've lost 12 lbs, and I finally understand my body."
Jessica S., 32
"I used to push through HIIT every day and wonder why I was exhausted and not losing weight. Ask Aggie explained exactly why — and what to do instead. Down 9 lbs in 6 weeks and I'm working out LESS. I wish I'd had this years ago."
Maria R., 28
"I was at a work dinner and had no idea what to order. I opened Bestie, typed the menu options, and Ask Aggie told me exactly what to choose and why. It felt like texting a genius friend who happened to know everything about hormones. I'm obsessed."
Zoe T., 34
"My hormonal acne is completely gone. I didn't even know it was connected to my cycle until Ask Aggie explained it. She told me exactly what was happening on Day 14 and what to eat to fix it. Six weeks later — clear skin for the first time since I was 18."
Linda K., 41

Meet Your Expert
I've been exactly where you are.
I spent years fighting my body — over-exercising, under-eating, wondering why nothing worked no matter how hard I tried. Then I discovered biohacking and cycle syncing, and everything changed.
I wrote a book about it. I built a supplement line around it. And now I've built Bestie so you can have me — and everything I know — in your pocket, every single day.
Ask Aggie AI is trained on years of research, my own healing journey, and thousands of questions women have asked me. It's not generic advice. It's your answer, for your body, on your cycle day.

Other apps are calendars — they tell you what happened. Bestie is a coach. It tells you what to do next, every single day, based on your exact phase. Ask Aggie AI is what makes it completely different to anything else out there — you can ask about a restaurant menu, a recipe, a symptom, a workout, and get a real personalised answer in seconds.
Yes. Ask about a restaurant menu. Ask about a recipe. Ask why you're tired. Ask why your skin is breaking out. Ask what workout to do today. Ask Aggie will give you a real, personalised answer based on your exact cycle day — not generic advice you could find on Google.
Yes. The app learns and adapts to your unique cycle, even if it's not a perfect 28 days. Ask Aggie can also provide specific guidance for irregular cycles and supporting cycle regularity naturally.
The app still works for you. Ask Aggie can guide you on how to work with your body while on hormonal contraception. Many women use the app to understand their bodies better and prepare for when they come off birth control.
Most women notice fewer cravings, less bloating, and a calmer mood within the first 2–3 weeks. More significant changes — clearer skin, better energy, easier weight management — typically come at the 6–8 week mark. The women who see the biggest results are the ones who commit to 6 months.
Yes — every plan includes a 7-day free trial. No commitment, cancel anytime. We want you to fall in love with Bestie before you pay a penny.
That's because everything you've tried was designed for a male body. The female hormonal cycle changes everything — hunger, fat storage, energy, metabolism. Bestie is the first system built around how your body actually works. You weren't failing the programs. The programs were failing you.
